Terrace

farming around a terraceA terrace is an earthen embankment that follows the contour of a hillside, breaking a long slope into shorter segments and intercepting the flow of water

How it helps...

  • Both water and soil quality are improved
  • Terraces with grass on front or back slopes can provide valuable nesting habitat

Benefits

  • Soil Erosion
  • Water Quality
  • Wildlife

Planning

  • Terraces are expensive to construct. They may be practical where rotations or residue management are insufficient for erosion control.
  • Terraces are designed to control runoff from a 10-year, 24-hour storm.
  • Terraces are best suited to fields with a uniform, moderate slope.
  • Other soil conservation practices may need to be used with terraces to prevent sedimentation of the channels.
  • Cropland widths between terraces are designed to match planting equipment width.
Maintenance
  • Remove accumulated sediment from channels and around pipe intakes.
  • Repair sections of the terrace embankment or channels that have eroded or have settled excessively; reseed and fertilize to maintain good vegetation.
  • Control burrowing animals, weeds, brush and trees.
  • Do not drive on or over terraces.
  • Avoid farming close to intakes, and repair or replace damaged intakes.
